TIRE-HEATING FU RNACE.

SPECIFICATION forming part of Letters Patent No. 370,398, dated september 27, vles?.

Application filed January 29, 1887. Serial No. 225,883. (No model.)

sume and apply gas or gasoline as the heating agent.

With this objectin View my invention consists in the novel construction of parts and their combination, as hereinafter will be fully described, and especially as pointed out in the claims made hereto.

In the accompanying drawings, forming a part of this specification, I have fully illustrated my improved apparatus, and therein Figure l is a plan View of the body of the apparatus, wherein one of the lids or covers is shown thrown back on its hinges; andV Fig. 2 is a central sectional view taken on the line a: wof Fi 1.

lfln the drawings like parts are denoted by similar letters or numerals of reference.

Ihe letter A designates the support or stand of the apparatus, which is of metal, and composed of the legs 1, preferably four in number, and of such length as will bring the top of the casing or tire-chamber at the desired height for convenient disposition of the tires placed therein. The top part of the legs is formed to take and hold the ioor or bottom of the tireheating chamber, and for this purpose may be extended outwardly at the tops, as at 2, to make a Wide flange to set under the iioor or bottom and be bolted in place, as seen at 3. The floor 4 consists of a broad plate-ring of metal, provided with a number of apertures, as 5. These apertures may be somewhat larger than the pipes which pass through them,

,in order that combustion shall be aided by the free admission of air to the interior of the heating-chamber. The iioor is secured to the legs by bolts, as stated, or any other proper means may be used.

The letters B B designate the walls of the heating-chamber. These consist of two cylinders-the former adapted to set on the outer edge of the bottom plate and the latter adapted to seton the inner edge of the bottom plate, substantially as shown, and in order that they may be held fixed in position the bottom plate is formed with rim-anges, as 6, on the inner and outer face edges,respectively. The cover consists of a plate-ring corresponding to the bottom, and is divided into sections 8, which are hinged or detachably set on the casing or chamber. Within the chamber are secured a number of benches, 9, or plates set on their edges, and arranged across the interior of the chamber. These benches or plates are secured in position by any suitable means, and have their upper edges arranged on a common plane, to serve as supports for the tires to be heated.

The foregoing embraces the description of the receptacle for the tires, and it remains to describe the apparatus by which the heat is applied.

On each of the legs or supports of the heating-chamber, as at l0, is a iange, in which is formed a bearing or hole,1l, and through these holes is passed the main pipe C, which consists of a continuous line of piping,or aline of pipe bent in a circle and having the meeting ends closed. It will thus be perceived that the piping serves a double purpose of bracing the structure and as the distributing-pipe of the heating agent. -Let into this pipe O are a number of pipes, I2, reaching into the heating-chamber of the apparatus and having on their upper ends suitable burners, 13, through apertures in which the gas or fumes of gasoline escape. T he burners are arranged at such height as to bring the iiames of the burning gases well up in the chamber, so that the tires shall be subjected to their full eiiect. The burners in apparatuses of large capacity are elongated, and are arranged to set across the chamber of the casing, in order that tires of different sizes may be. arranged in concentric order and be heated.

The numeral I4 designates the pipe leading The use of the apparatus is readily perceived IOO from the foregoing description; but it may be here stated the tire is laid in the open heatingchamber and the covers closed, after which the gas is turned on and lighted and the heat applied until the proper degree is reached,when the iiow can be turned off', the covers lifted up, and the tires removed.

I have not shown the apparatus as con nected to a gasolinereservoir,for thereason that such reservoir may be of any proper construction, and forms no part of my invention.

I am aware that a tire-heating furnace of the general character of mine is old, that legs or supports of Various kinds have been used with such older forms of furnaces, and that air has been admitted intosuch furnaces or chambers by various means, one being a circular tuyere having nozzles opening into the heatingchamber. All of such older constructions I disclaim, and seek protection only for the invention which I have set forth in the claims hereof.

What I claim as my invention, and desire to secure by Letters Patent, isn

l. The tire-heating apparatus composed of a ring-form bottom plate having apertures therein,concentric cylinders forming the walls of the chamber, and sectional covers, and

avoea benches or supports across the interior of the chamber, between the walls thereof, and supports secured to the bottom plate, in combination with a gas-burning apparatus composed of a line of piping passed through bearings l1 in anges carried by the supports of the chamber, and having a number of pipes projected therefrom into the chamber and terminating in burners, whereby the supports are braced and the gas conducted to the fire-chamber, substantially as specified.

2. The combination of a tire-heating chamber, provided with supports, with aline of gaspipe fixed rigidly to said supports, and pipes terminating in burners projected-from said line of gaspipes into the tire-heating chamber, and a feed-pipe opening into the pipe held by the support,substantially as described, and for the purpose stated.

' In witness whereof I have hereunto set m hand in the presence of two attesting witnesses.
